When I open a TM from the Translation memory panel I can only see a few segments. How can I view the whole TM? How can I find out how many segments the TM is made up of? I was told I could move one page forward or backward page by clicking on the blue arrows in the toolbar on the top. However, I still cannot see all the pages that make up a TM. I can see a blue bar on top of the "list" of TU, and there are two arrows on the right side but they seem to be grayed out, and nothing happens when I click on them. In the "list" of TU I got there are some numbers missing (I got 2, 6, 7, 9, 11, 15 and so on). Any idea of why this is happening?
